.TH std::flat_multimap::max_size 3 "2024.06.10" "http://cppreference.com" "C++ Standard Libary"
.SH NAME
std::flat_multimap::max_size \- std::flat_multimap::max_size

.SH Synopsis
   size_type max_size() const noexcept;  (since C++23)

   Returns the maximum number of elements the container is able to hold due to system
   or library implementation limitations. Equivalent to
   std::min<size_type>(c.keys.max_size(), c.values.max_size()).

.SH Parameters

   \fI(none)\fP

.SH Return value

   Maximum number of elements.

.SH Complexity

   Constant.

.SH Notes

   This value typically reflects the theoretical limit on the size of the container, at
   most std::numeric_limits<difference_type>::max(). At runtime, the size of the
   container may be limited to a value smaller than max_size() by the amount of RAM
   available.

.SH Example


// Run this code

 #include <iostream>
 #include <flat_map>
 #include <locale>

 int main()
 {
     std::flat_multimap<char, char> q;
     std::cout.imbue(std::locale("en_US.UTF-8"));
     std::cout << "Maximum size of a std::flat_multimap is " << q.max_size() << '\\n';
 }

.SH Possible output:

 Maximum size of a std::flat_multimap is 768,614,336,404,564,650
